Specification of Letters Patent. Prent'ed Sept, 26, .1911.

Application led Novembery Il, 19,09. Serial No. 526,245.

lg 'all whom fit may concern: Be it known that I, JOHN Harm-ion, a citizen; of the United States, residing at Hous` ton, in the county of Harris and State of Texas, *have invented certain new and useful Improvements in llVheels, of which the following is a specification.

[My invention relates tonew and useful improvements in wheels, and more particularly in that class of wheels designed with special reference for' usel on barrows and trucks. f

.'lh'e object. of the invention is to' 'provide a wheel of the character described that will at `once be strong and light and willbe capable of withstanding an unusual amount 0f strain in proportion to the amount of material therein.

Another feature resides in the provision of a novelly constructed hub which is contrived with special reference to the attainment of great strength. A further4 feature of the invention resides in the provision ofian internal oil chamber, Within thelhub, arranged for the lfVith the above and other objects in view my invention has particular relation to certain novel` features of construction and arrangement of parts, an example of which is given lin this specification and illustrated in the accompanying' drawings, wherein:-

Figure 1 .is a side elevation of the Wheel, and Fig. 2 is a vertical diametrical sectionalview thereof.

Referring now more particularly to the' drawings, wherein like numerals of reference designate similar parts in each of the' 'figures, the numeral 1 refers to a circular metallic disk or plate whichcomprises the main body of the wheel'. This plate has a central opening,l ofa size sufficient to provide for the hub and is also providedV with a 'series of openings 2, alined concentric with the central opening and of such a size as to make the wheel as light as possible consistent with the desired strength thereof.

For a rim or folly of the wheel I have provided two angle irons 3 and 4 which have been formed in a circular shape, as shown in thegurcs,and secured to the periphery of plate-1 in the manner presently to be describedz-'lhesaid angle ironsl have first been formed so that one of the webs of each l will be parallel t the axial line of the Wheels and the other web will be perpendicular.

thereto, and the tivo irons are, then Secured" to the outer edge of the circular plate 1, yin such a manner that the said parallel webs 60 `will .he in exact alinement with eachother,

andthe perpendicular webs will embrace theouteredge of said plate, as shown `infFi 2, the. periphery of the plate being flush wit the periphery of. ;he angle irons.'

A plurality of bolts or rivets 5 arethen 65 -passed through the inner websl and the joints.

In the formation of the hub of the .wheel l I have provided conicalshaped castings 7 and 8 the faces of which are designed to rest .80 against the inner edge o f plate 1, and surround the central opening thereof. The apexes of these castings are prolonged intl) cylindrical shaped bearing members 9, and 10. In order' to secure the members Landi 'g5 8 in their proper positionI have provided conical shaped collars11` and' 12, o` y a size suflicient to fit snugly over the castings L7 and 8 respectively. ,The bases'of these colf' lars are prolonged into circular flangesfl' 9o and 14 which embrace plate-1 ,from oppositel ,sides and are secured thereto l"by means of rivets 15 which pass through the fianges and the plate. I`he apexespf the collars areialso A: prolongednto cylindricalshaped flanges 16 9i;

vand 17 which closelyfsurround members-9 and 10 respectively. The angle which the sloping sides ofthe castings? and 8 and collars 11 and 12 bear to the plateI andthe axial line of the wheel may be .varied in 10( order to give the desired-strength, i The arch effect which this construction'. gives to the hub will be found to'impartgreat si rengththereto and thus preserve the wheel against warping. i i

As is readily obvious` the hubis provided with an internal chambenIS. I have' provision whereby thi's chamber maygvbelfuti? lized for the purpose of oiling the earin of the wheel. A small orifice passes throufgf` collar 11 and casting? and communicates with chamber 18. This orifice is provided portionfof this lubricant is carried around upon the inner walls of the chamber and radually runs down said walls onto shaft 20, which passes axially through the bearing members 9 and 10, and works outwardly along. the shaft and 'keeps the bearings oiled.

A wheel constructed in accordance with the foregoing description and the drawings accompanying the-same, and made a part thereof, will be found to be easily and cheaplyconstructed, automatically oiled in its bearings, and will further possess lightness and durability the two priiiie Virtues sought to be attained. l

What I claim is In a wheelof the character described, a

hub comprising a diskhaving a central opening therethrough, two opposing cone shaped members whose bases rest against said disk on opposite4 sides andvsurround said central opening, said cone shaped members having their bases concaved so as to leave a central chamber Within said hub, bearing members integral with said cone shaped members and continuing from the apexes thereof, similar cone shaped collars fitting over said cone shaped members and means for securing the said collars to the disk.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
